Pro Mini 328P - 3.3V / 8MHz - ATmega328P with Bootloader - Bascom AVR - Arduino Compatible
Universal module with ATmega328P microcontroller. Can be used in many microprocessor projects. The board is compatible with Arduino PRO MINI 3V 8MHz project. The microcontroller has a bootloader loaded, so all you need to program it is a UART programmer.
Are you interested in electronics or programming? If so, Arduino is just for you because it links these two worlds! Thanks to microprocessors you will implement various projects!
Product features
3.3V version.
Pro Mini, like UNO, is based on the popular Atmega328P microcontroller.
The board contains the ATmega328P chip, equipped with 14 digital inputs / outputs, 6 of which support the PWM signal (e.g. for servo control), and 8 analog inputs (for voltage measurement), but they can also act as additional digital pins (22 inputs / outputs in total).
Works with voltages of 3.3V.
It is clocked with a 8 MHz clock signal.
Switch for manual reset.
This version does not have soldered connectors - so the board can keep its small size.

Additional information
Power
If the supply voltage is higher than 3.3V, it should be connected to the RAW output, which is connected to the stabilizer (then the max voltage is 12V).
VCC is connected directly to the pins of the microcontroller, connecting a voltage higher than 5V may permanently damage the board.
Inputs / outputs
Arduino Pro has 14 digital inputs / outputs (I / O).
Each pin allows the consumption of current with a maximum intensity of 40mA, which allows direct connection of LEDs with resistors and control of other integrated circuits.
In addition to the standard I / O, some outputs also have special functions.
Programming
Creating and uploading software is possible thanks to the free environment provided by the manufacturer.
Arduino Pro does not have a chip that controls the USB interface. Therefore, the programming requires a UART <-> USB adapter.
For programming, you can use the PL2303 programmer or the AVR ISP programmer
